Problems solved by technology

[0009] However, if Figure 2B As shown, the node number or link number defined in the road network needs to be replaced with a new number when the road d is newly set or the road is changed, and when the node number or link number is changed, the numbers of each company must be updated map data
[0010] New establishment or changes of roads will continue in the future. Therefore, as long as the road position representation method using node labels or link numbers as in the past is used, a huge amount of work must be continuously invested and accompanied by the maintenance of the digital map database. The cost of having such maintenance becomes a problem of great burden

Abstract

Even if an object having a shape similar to that of a specific object is present near the specific object, the position information representing the position of the specific object is transmitted, andthe specific object can be identified more accurately on the basis of the position information. When a shape data creating section (110) of a position information transmitter (100) creates shape dataand transmits it to a position information receiver (200), a wrong identification judging section (120) previously performs the same road-identification processing as that of a wrong identification judging section (220) of a position information receiver (200). If a road which may be identified wrongly is identified, an additional information adding section (130) adds additional information so asto identify a road, a transmission data creating section (140) adds the distance from the first portion of the road and the degree of congestion to the shape data to thus create transmission data, and a data transmitting section (150) transmits data to the position information receiver (200).

Description

technical field [0001] The present invention relates to an information transmission method for transmitting road location information indicating road locations where congestion, accidents, etc. occur in a system for providing traffic information, etc., and a device for exchanging information about locations using the method, in particular to a A positional information transmitting device, a positional information receiving device, a positional information transmitting method, and a positional information transmitting program in a positional information exchange system capable of reliably and quickly transmitting positions on a digital map. Background technique [0002] In recent years, there has been a rapid increase in the number of vehicles equipped with on-board navigation devices. The vehicle navigation system used by the vehicle navigation machine maintains a digital map database, and based on the latitude and longitude data received by the GPS receiver, it can display ...
